Ionic tabs hiding content

ionic-v1
1

Hi folks! I’m developing an app and I want a view with some tabs, but my header bar overlaps the content

<ion-header-bar align-title="left" class="bar-dark">
    <h1 class="title">Header</h1>
</ion-header-bar>

<ion-tabs>
    <ion-tab title="info">
        <ion-content class="has-header" padding="true">
            <h2>Tab 1 Content</h2>
        </ion-content>
    </ion-tab>
    <ion-tab title="Openingsuren">
        <ion-content class="has-header" padding="true">
            <h2>Tab 2 Content</h2>
        </ion-content>
    </ion-tab>
</ion-tabs>

I hope someone can help… Thank you in advance!!
